extends from top to bottom and is separated I To all whom it may concern.-

Be it known that l, HARRY B. CORNISH, of Hampton, in the county of Franklin and State of Iowa, have invented a new and Improved Combined Refrigerator and Gas-Generator, of which the following is a full, clear, and exact description.

Myinvention relates to a combined refrigerator and gas-generator, and has for its object to provide means whereby the cooling of refrigerators, refrigerator-cars, and cold-storage compartments may be effected by the use of gasoline or other volatile fluid in conjunction with. compressed air and an atomizer; and a further object of the invention is to provide a means whereby the gas to be generated by the air and fluid forced through the atomizer will be sprayed into coils of pipe located in the compartment to be cooled, and whereby also all the fluid not generated into gas will condense and find its way back to thefluid-receptacle.

Another object of the invention is to conduct the gases away'from the compartment to be refrigerated to a burner or gasometer for the purpose of producing light.

The invention consists'in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the refrigerator, sundry compartments being exposed. Fig. 2 is a horizontal section taken, practically, on the line 2 2 of Fig. 1. Fig. 8 is a vertical section taken, practically, on the line 3 3 of Fig. 2. Fig. 4 is'a vertical section taken near one end of the refrigerator upon the line a 40f Fig. 2. Fig. 5 is avertical section taken near the opposite en d of the refrigerator upon the line 5 5 of Fig. 2, and Fig. 6 is a detail view of the atomizer.

The invention is shown in the drawings in connection with a refrigerator A, the case of which may be of any suitable or approved construction. The case, however, is preferably divided into two compartments B and O. The compartment B is at one side and from the compartment 0 by the partition 10. The compartment 0 likewise extends from top to bottom, and is larger than the compartment B.

The compartmentB is provided with a door 11, which exposes it from top to bottom, and

the compartment 0 is also provided with a.

door 12, located at the upper portion thereof and exposing about one-half, as illustrated in Fig. 1. In the lower portion of the compartment O a reservoir 13 is located, which may be of any desired shape, but is preferably Inade cylindrical. adapted to contain compressed air, and upon the reservoir 13 a tank let is placed and supported above the reservoir, the said tank 14 being made to correspond in shape, preferably, to the cross-sectional contour of the compartment in which it is located. As this compartment is illustrated as square, or prac tically so, the tank is also rectangular. This tank is adapted to contain gasoline or other volatile liquid, and the top of the tank constitutes the bottom of the refrigerator-chamber 15, which chamber is formed by back and side ,walls 16 being projected upward from the tank to a connectionwith an upper horizontal wall-17. Within this chamber 15 coils of pipe 18, 19, and 20 arelocated. Any desired number of coils may be employed, and they maybe placed as found most advantageous. Ordinarily, however, the coil 18 is located near the top of the chamber, the coil 19 at the back, and the coil 20horizontally at or aboutits center. These coils are connected in any approved manner and are supported by ordinary devices in their relative positions.

The compartment or chamber 15 is'not ordinarily as wide or as long as the compartment O-that is, a space 21 is produced at one end, as is best shown in Fig. 2.: The upper end of the coil extends outward through one side wall of the chamber 15 into the space 21, and into this pipe (shown and designated as a in Fig. (i) the upper reduced end. 22 of a pipe 23 is inserted. That end of the pipe within the coil-section a is conical, and its opening is comparatively small. The pipe 23 extends downward in the space 21, and is introduced into the end of the reservoir 13 at or This reservoir is near the bottom thereof, as shown in Fig. -l, the said pipe being provided at a convenient point with a valve 24, the stem of which extends outward through the boX. A second pipe 25, also provided with a valve 26 and extending through the box, emanates from the end of the reservoir at or near the top thereof, and is carried upward to a point at or near the top of the pipe 223, and in conjunction with these two pipes an atomizer 27 is employed, as illustrated in Fig. 6, the atomizer connecting with the pipe 25 and passing through the coil-pipe a in close proximity to the reduction 22 of the pipe 23. The tank l-l is also connected with the upper portion of the reservoir 13 by a pipe 28, provided with a valve 29, likewise operated from the exterior of the box. The lower end of the coil passes outward from the wall of the chamber 15 and connects with a discharge pipe 30, which pipe is carried out through the box at any convenient point to a connection with any approved form of gasometer or gas-burner, and the discharge-pipe 30 is connected with the tank 14: through the medium of a branch pipe 31, as is best shown in Fig. i.

In the compartment B an air-pump 32, of any approved type, is located, the piston of which pump is operated by a lever 33, suitably fulcru med at or near its center, and the said lever is provided with a handle 3i, pivoted to and adjustable thereon, which handle is provided with a spur 85, adapted to enter an aperture 36 in the lever. hen the airpump is not being operated, the handlehangs down, as shown in Fig. 5, at a right angle to the lever, thus permiting the door 11 to be closed. iVhen it is desired to use the pump, however, the handle is carried upward to a horizontal position, at which time it will extend out beyond the front of the box, and its spur 35 is made to enter the lever-aperture 36.

In operation when gasoline or other volatile liquid has been placed in the tank 11 in sutficient quantity and the reservoir 13 is charged with compressed air, the valve 29 is opened and a proper quantity of liquid is permitted to flow from the tank into the air-reservoir, whereupon it will sink to the bottom of the latter. The valves 24 and 26 are then opened as far as desired, and the air from the reservoir will pass upward through the air-pipe 25 to the atomizer 27, and the air blowing from the atomizer across the contracted end of the pipe 23 creates a suction, and the liquid in the bottom of the reservoir flows upward through the latter pipe, and upon leaving the pipe is impinged upon by the compressed air passing through the atomizer and is sprayed in the form of a gas into the coil of pipe. The gas circulating through the coils of pipe effectually cools the chamber 15, and in leaving the coils the gas enters the discharge-pipe 30, whereupon all the liquid not generated into gas will condense and find its way through the branch pipe 31 into the tank 14, while the gas will pass off to the burner or gasometer heretofore referred to, to be used as an illuminating medium.

It is evident that the device is very simple, economic, and eft'ective in its operation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a receptacle, means for filling the receptacle with compressed air, a tank adapted to contain a volatile liquid, located near the air-receptacle, and a valve connection between the tank and the air-receptacle, of acoil of pipe located within a chamber, a valved pipe extending from the air-receptacle near the top thereof to a point near the top of the coil, a second valved pipe extending from the lower portion of the airreceptacle and projected into the upper portion of the coil, and an atomizer connecting the upper ends of the two pipes, one of which pipes is for airand the other for liquid, substantially as shown and described.

2. The combination, with a receptacle and means for charging said receptacle with compressed air, a tank located above the receptacle and adapted to contain a volatile liquid, a connect-ion between the tank and the upper portion of the air-receptacle, and a coil of pipe located within the chamber, of a valved air-escape pipe leading from the upper portion of the air-receptacle to a close proximity to the upper portion of the coil, a liquid-escape pipe leading from the bottom of the airreceptacle and connected with the upper portion of the coil, an atomizer connecting the air-escape pipe and the liquid-escape pipe within the coil, a discharge-pipe connected with the lower end of the coil, and a branch pipe connecting the discharge-pipe with the tank, as and for the purpose specified.
